| 2022-07-08 | channels: Emit version 3 profiles....Fixes <https://issues.guix.gnu.org/56441>.
Reported by zimoun <zimon.toutoune@gmail.com>.
Fixes a bug introduced in 4ff12d1de7cd617b791996ee7ca1240660b4c20e with
version 4 of the manifest format. A new 'guix time-machine' would
create a v4 manifest; when targeting an old revision (v3),
'generate-package-cache' would fail to read that manifest and abort.
Furthermore, an old Guix living in a new profile with a v4 manifest
would be unable to describe itself via (guix describe).
* guix/channels.scm (package-cache-file): Add 'format-version' field to
PROFILE.
(channel-instances->derivation): Pass #:format-version to
'profile-derivation'.

| 2022-06-16 | channels: Print backtrace when generating package cache fails....* guix/channels.scm (package-cache-file): Add a throw handler around
the generate-package-cache call, and print backtrace in it.

| 2021-09-18 | channels: 'channel-news-entry-commit' correctly resolves annotated tags....Previously, 'channel-news-entry-commit' would return the tag ID rather
than the commit ID when the news entry was referred to via an annotated
tag.
Reported by Xinglu Chen <public@yoctocell.xyz>.
* guix/channels.scm (resolve-channel-news-entry-tag): Check whether the
reference points to annotated tag; resolve it if it does.
* tests/channels.scm ("channel-news, annotated tag"): New test.
| Ludovic Courtès |
| 2021-05-12 | channels: Add a #:system argument to channel-instances->manifest....This allows computing a manifest for a specific system. Previously this was
possible, but only through changing %current-system, which caused the
derivation to be computed using that system as well (so computing a derivation
for aarch64-linux on x86_64-linux would require running aarch64-linux code).
This new argument adds the possibility of computing derivations for non-native
systems, without having to run non-native code.
I'm looking at this as it will enable the Guix Data Service to compute channel
instance derivations without relying on QEMU emulation for non-native
systems (it should be faster as well).
* guix/channels.scm (build-from-source): Add #:system argument and pass to
build.
(build-channel-instance): Add system argument and pass to build-from-source.
(channel-instance-derivations): Add #:system argument and pass to
build-channel-instance, also rename system to current-system-value.
(channel-instances->manifest): Add #:system argument and pass to
channel-instance-derivations.

| 2021-02-04 | channels: Consider the current channel commit as authentic....Fixes <https://bugs.gnu.org/45895>.
When the ~/.cache/guix/authentication is empty, this change allows
authentication to start at the current commit, as shown by 'guix
describe', instead of starting from the introductory commit, which would
take more and more time (there's currently 18K commits per year).
* guix/git-authenticate.scm (authenticate-repository): Add #:authentic-commits.
[authenticated-commits]: Append it.
* guix/channels.scm (authenticate-channel)[authentic-commits]: New
variable. Pass it to 'authenticate-repository'.

PROFILE.
(guix-describe): When PROFILE is #f, call 'current-channels' and pass it

Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>.
The "channel-instances->manifest" test would fail since
1d4ab335b22a93e01c2eb1eb3e93fc6534157040: 'quiet-guile' would be passed #f
as GUILE, and thus 'package-version' would fail with wrong-type-arg.

| 2020-07-01 | channels: Remove 'signature' from <channel-introduction>....In the end signing the commit/key pair does not buy us much. Someone
publishing a valid but different commit/key pair would effectively be
publishing a different channel, which could be a fork (made by a former

| 2020-06-21 | channels: 'authenticate-channel' doesn't check relation with intro commit....Fixes <https://bugs.gnu.org/41908>.
Reported by Jan Nieuwenhuizen <janneke@gnu.org>.
The relation check imposed an extra restriction that was unnecessary:
it's enough to authenticate the set difference between the closure of
START-COMMIT and that of END-COMMIT. Any attempt to jump to an
unrelated commit would lead to the authentication failure of one commit
on the way.

or similar because the target Guix would be built with 2.2, and then
we'd erroneously go on and attempt build the profile with 2.2. This
